Polarization signature information is becoming more useful as an added discriminant in a variety of signature analysis
applications. However, there are few infrared scene projection systems that provide the capability to inject target
simulation images with polarization content into a seeker, or other imaging sensor. In this paper, we discuss a
polarization scene generator (PSG) concept that is applicable to testing sensor systems operating in cryogenic-vacuum
environments. This polarization scene generator concept demonstrator system was constructed from off-the-shelf
technology using commercially available mid-wave infrared (MWIR) scene projectors based on micromirror device
display technology, standard infrared polarizers, and standard IR cameras. The demonstrator system used two digital
micromirror device (DMD)-based displays, each projecting orthogonal polarization states, which were then combined to
generate images with pixels having independent S1 or S2 polarization content. This concept is robust because it is
relatively unconstrained by the IR scene generators used or by the seekers tested. This paper discusses the test results of
the concept demonstrator system with regard to sensitivity to misalignment, radiance mismatch, and display uniformity.
